The processes for preparing the object compound [I] are explained in detail in the following.

Process 1

The object compound [I] or its salt can be prepared by reacting a compound [II] or its salt with a compound [III] or its salt.

Suitable salts of the compounds [II] and [III] may be the same as those exemplified for the compound [I].

The reaction is preferably carried out in the presence of a base such as alkali metal [e.g. lithium, sodium, potassium, etc.], the hydroxide or carbonate or bicarbonate thereof [e.g. sodium hydroxide, potassium carbonate, potassium bicarbonate, etc.], alkali metal alkoxide [e.g. sodium methoxide, sodium ethoxide, potassium tert-butoxide, etc.], or the like.

This reaction is usually carried out in a conventional solvent such as tetrahydrofuran, dioxane, N,N-dimethylformamide, acetone, or the like.

The reaction temperature is not critical, and the reaction is usually carried out under cooling to heating.

Process 2

The object compound [Ib] or its salt can be prepared by acylating a compound [Ia] or its salt.

The acylation is carried out in the presence of an acylating agent.

Suitable acylating agents are the corresponding carboxylic acid or sulfonic acid compounds, which are represented by the formula: R--OH wherein R is acyl, and reactive derivatives thereof, and the corresponding isocyanate or isothiocyanate compounds.

As suitable said reactive derivatives, there may be mentioned acid halides, acid anhydrides, active amides and active esters. Suitable examples are acid halides such as acid chloride and acid bromide, mixed acid anhydrides with various acids [e.g. substituted phosphoric acid such as dialkyl phosphoric acid, sulfuric acid, aliphatic carboxylic acid, aromatic carboxylic acid, etc.], symmetric acid anhydrides, active amides with various imidazoles, and active esters such as p-nitrophenyl ester and N-hydroxysuccinimide ester. The kind of such reactive derivatives can be selected depending on the kind of acyl group to be introduced.

The reaction is usually carried out in a conventional solvent, such as methylene chloride, chloroform, pyridine, dioxane, tetrahydrofuran, N,N-dimethylformamide, or the like. In case that the acylating agent is liquid, it can also be used as a solvent. In case that the carboxylic acid or sulfonic acid compounds are used as acylating agent in the free acid form or salt form, it is preferable to carry out the reaction in the presence of a conventional condensing agent such as N,N'-dicyclohexylcarbodiimide or the like.

The reaction temperature is not critical and the reaction can be carried out under cooling, at ambient temperature, or under heating.

This reaction is preferably carried out in the presence of a conventional inorganic base or in the presence of a conventional organic base.

Process 3

The object compound [Id] or its salt can be prepared by acylating a compound [Ic] or its salt.

This reaction can be carried out in substantially the same manner as Process 2, and therefore the reaction mode and reaction condition of this reaction are to be referred to those explained in Process 2.

Process 4

The object compound [If] or its salt can be prepared by reacting a compound [Ie] or its reactive derivative at the carboxy group or a salt thereof with a compound [IV] or its reactive derivative at the amino group or a salt thereof.

Suitable reactive derivative at the carboxy group of the compound [Ie] may include an acid halide, an acid anhydride, an activated amide, an activated ester, and the like. Suitable examples of the reactive derivatives may be an acid chloride; an acid azide; a mixed acid anhydride with an acid such as dialkylphosphoric acid, sulfuric acid aliphatic carboxylic acid or aromatic carboxylic acid; a symmetrical acid anhydride; an activated amide with imidazole; or an activated ester [e.g. p-nitrophenyl ester, etc.]. These reactive derivatives can optionally be selected from them according to the kind of the compound [Ie] to be used.

Suitable reactive derivative at the amino group of the compound [IV] may be a silyl derivative formed by the reaction of the compound [IV] with a silyl compound such as bis(trimethylsilyl)acetamide or mono(trimethylsilyl)acetamide, or the like.

Suitable salts of the compound [IV] and its reactive derivative can be referred to the organic or inorganic acid addition salts as exemplified for the compound [I].

This reaction can be carried out in substantially the same manner as Process 2, and therefore the reaction mode and reaction condition of this reaction are to be referred to those explained in Process 2.

The object compound [I] and the starting compounds can also be prepared by the methods of Examples and Preparations mentioned below or similar manners thereto or conventional manners.

The compounds obtained by the above processes can be isolated and purified by a conventional method such as pulverization, recrystallization, chromatography, reprecipitation or the like.

It is to be noted that the compound [I] and the other compounds may include one or more stereoisomers and geometrical isomers due to asymmetric carbon atoms and double bonds, and all of such isomers and mixture thereof are included within the scope of this invention.

The object compound [I] and pharmaceutically acceptable salts thereof possess strong activities as bradykinin antagonists, and are useful for the treatment and/or the prevention of bradykinin or its analogues mediated diseases such as allergy, inflammation, autoimmune disease, shock, pain, or the like, and more particularly for the prevention and/or the treatment of asthma, cough, bronchitis, rhinitis, rhinorrhea, obstructive pulmonary disease [e.g. pulmonary emphysema, etc.], expectoration, pneumonitis, systemic inflammatory response syndrome (SIRS), septic shock, endotoxin shock, anaphylactic shock, adult respiratory distress syndrome, disseminated intravascular coagulopathy, arthritis, rheumatism, osteoarthritis, lumbago, inflammation-induced bone resorption, conjunctivitis, vernal conjunctivitis, uveitis, iritis, iridocyclitis, headache, migraine, toothache, backache, superficial pain, cancerous pain, postoperative pain, tenalgia, trauma [e.g. wound, burn, etc.], rash, erythema, eczema or dermatitis [e.g. contact dermatitis, atopic dermatitis, etc.], urticaria, herpes, itching, psoriasis, lichen, inflammatory bowel disease [e.g. ulcerative colitis, Crohn's disease, etc.], diarrhea, hepatitis, pancreatitis, gastritis, esophagitis, food allergy, ulcer, irritable bowel syndrome, nephritis, angina, periodontitis, edema, hereditary angioneurotic edema, cerebral edema, low blood pressure, thrombosis, myocardial infarction, cerebral vasospasm, congestion, coagulation, gout, central nervous system injury, premature labor, arteriosclerosis, postgastrectomy dumping syndrome, carcinoid syndrome, altered sperm mobility, diabetic neuropathy, neuralgia, graft rejection in transplantation, or the like, in human being or animals.

In order to illustrate the usefulness of the object compound [I], the pharmacological test data of some representative compounds of the compound [I] are shown in the following.

³ H-Bradykinin receptor binding

(i) Test Method:

(a) Crude ileum membrane preparation

Male Hartly strain guinea pigs were sacrificed by decapitation. The ileum was removed and homogenized in buffer (50 mM trimethylaminoethanesulfonic acid (TES), 1 mM 1,10-phenanthroline pH 6.8). The homogenate was centrifuged (1000×g, 20 minutes) to remove tissue clumps and the supernatant was centrifuges (100,000×g, 60 minutes) to yield a pellet. The pellet was resuspended in buffer (50 mM TES, 1 mM 1,10-phenanthroline, 140 mg/l bacitracin, 1 mM dithiothreiol, 0.1% bovine serum albumin pH 6.8) and homogenized with a glass-teflon homogenizer to yield suspension which was referred to as crude membrane suspension. The obtained membrane suspension was stored at -80° C. until use.

(b) ³ H-Bradykinin binding to the membrane

The frozen crude membrane suspension was thawed. In binding assays, ³ H-Bradykinin (0.06 nM) and drug (1×10⁻⁶ M) were incubated with 50 μl of the membrane suspension at room temperature for 60 minutes in a final volume of 250 μl. Separation of receptor-bound from free ³ H-Bradykinin is achieved by immediate filtration under vacuum and washed three times with 5 ml of ice-cold buffer (50 mMTris-HCl pH 7.5).
